Abstract
Abstract An apparatus for use in positioning a suture anchor includes a tubular outer member and an inner or pusher member. During assembly of the apparatus, a suture is positioned in a slot in the outer member. During use of the apparatus, the slot facilitates visualization of the position of the suture anchor relative to body tissue. In addition, the slot facilitates separation of the apparatus from the suture after the suture anchor has been positioned in the body tissue. A suture anchor retainer may be provided at one end of the tubular outer member to grip the suture anchor and hold the suture anchor in place during assembly. The suture anchor retainer also holds the suture anchor during movement of the apparatus from an assembly location to an operating room or other location where the apparatus is to be used. Indicia may be provided on the inner member to indicate the position of the suture anchor relative to body tissue. The tubular outer member may be utilized to guide a drill during formation of an opening in body tissue and may be subsequently utilized to guide movement of a suture anchor into the opening in the body tissue.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
A method of positioning a suture anchor connected with a suture relative to body tissue, said method comprising the steps of moving a pusher member into a passage in a tubular member, transmitting force from the pusher member to a trailing end portion of an anchor to move the anchor out of the tubular member into body tissue, determining when the anchor has moved through a desired distance from the end portion of the tubular member into body tissue by viewing indicia which is connected with the pusher member and moves with the pusher member relative to the tubular member, and interrupting movement of the pusher member into the passage in the tubular member in response to a determination that the suture anchor has moved through a desired distance into the body tissue from the end portion of the tubular member.
Claim 2
Independent Claim
141 words
A method of positioning a suture anchor connected with a suture relative to body tissue, said method comprising the steps of moving a pusher member into a passage in a tubular member, transmitting force from the pusher member to a trailing end portion of an anchor to move the anchor out of the tubular member into body tissue, determining when the anchor has moved through a desired distance from the end portion of the tubular member into body tissue by viewing indicia which is connected with the pusher member and moves with the pusher member relative to the tubular member, and interrupting movement of the pusher member into the passage in the tubular member in response to a determination that the suture anchor has moved through a desired distance into the body tissue from the end portion of the tubular member.
Claim 3
Independent Claim
157 words
A method of positioning a suture anchor connected with a suture relative to body tissue with a suture anchor inserter assembly, said method comprising the steps of positioning a leading end portion of an inserter member forming part of the inserter assembly in an opening in the suture anchor, pushing the suture anchor into body tissue under the influence of force transmitted through the inserter assembly to the suture anchor, sliding a tapered end of the leading end portion of the inserter member along an inner side surface of the opening in the suture anchor while the suture anchor is disposed in the body tissue, and changing the orientation of the suture anchor relative to the tapered end of the leading end portion of the inserter member while performing said step of sliding the tapered end of the leading end portion of the inserter member along the inner side surface of the opening in the suture anchor.
Claim 4
Independent Claim
157 words
A method of positioning a suture anchor connected with a suture relative to body tissue with a suture anchor inserter assembly, said method comprising the steps of positioning a leading end portion of an inserter member forming part of the inserter assembly in an opening in the suture anchor, pushing the suture anchor into body tissue under the influence of force transmitted through the inserter assembly to the suture anchor, sliding a tapered end of the leading end portion of the inserter member along an inner side surface of the opening in the suture anchor while the suture anchor is disposed in the body tissue, and changing the orientation of the suture anchor relative to the tapered end of the leading end portion of the inserter member while performing said step of sliding the tapered end of the leading end portion of the inserter member along the inner side surface of the opening in the suture anchor.
Claim 5
Dependent Claim
51 words
A method as set forth in claim 2 wherein said step of changing the orientation of the suture anchor relative to the tapered end of the leading end portion of the inserter member includes pivoting the suture anchor about the tapered end of the leading end portion of the inserter member.
Claim 6
Dependent Claim
43 words
A method as set forth in claim 2 further including the step of tensioning a suture connected with the suture anchor to pivot the suture anchor relative to body tissue under the influence of force transmitted through the suture to the suture anchor.
Claim 7
Dependent Claim
56 words
A method as set forth in claim 4 wherein said step of tensioning the suture to pivot the suture anchor is at least partially performed after performance of said step of sliding a tapered end of the leading end portion of the inserter member along an inner side surface of the opening in the suture anchor.
Claim 8
Dependent Claim
66 words
A method as set forth in claim 2 wherein said step of sliding a tapered end of the leading end portion of the inserter member along an inner side surface of the opening in the suture anchor includes sliding a point on the tapered end of the leading end portion of the inserter member along an inner side surface of the opening in the suture anchor.
Claim 9
Dependent Claim
103 words
A method as set forth in claim 2 wherein said step of sliding a tapered end of the leading end portion of the inserter member along an inner side surface of the opening in the suture anchor includes engaging a portion of an entrance to the opening in the suture anchor with a first location on the leading end portion of the inserter member and engaging the inner side surface of the opening in the suture anchor with an end of the tapered end portion of the inserter member at a location spaced from the entrance to the opening in the suture anchor.
Claim 10
Dependent Claim
220 words
A method as set forth in claim 2 wherein the leading end portion of the inserter member has a circular cross sectional configuration as viewed in a plane extending transversely to a longitudinal central axis of the inserter member and the opening in the suture anchor has a circular cross sectional configuration as viewed in a plane extending transversely to a longitudinal central axis of the opening in the suture anchor, said step of sliding a tapered end of the leading end portion of the inserter member along an inner side surface of the opening in the suture anchor includes engaging a first portion of an entrance to the opening in the suture anchor with a first location on the leading end portion of the inserter member while a second portion of the entrance to the opening in the suture anchor is spaced from the leading end portion of the inserter member and engaging a first portion of the inner side surface of the opening in the suture anchor with a second location on the leading end portion of the inserter member while a second portion of the inner side surface of the opening located diametrically opposite from the first portion of the inner side surface of the opening is spaced from the leading end portion of the inserter member.
